Episode 4 — Your first agent
An agent built end to end on camera in the earlier agent editor — name, instructions, knowledge scope, tools, model — with the trust boundary spelled out; the screens have changed since, the reasoning has not.

Chat taught you to ask; knowledge taught you what answers stand on. This episode builds the thing that puts both to work: an agent, created from scratch on camera. The through-line is the trust boundary — every tool you grant widens what the agent can do, so the smallest agent that does the job is the safest one.

| At | Scene |

| 0:13 | The agents list — builtins, and where yours will live |
| 0:26 | Create: a technical name, a display name, continue |
| 0:43 | Instructions — the job description, including the hand-off rule |
| 1:00 | Knowledge scope: the smallest library that does the job |
| 1:13 | Tools: capability is exposure — start with none |
| 1:33 | The model and its fallback |
| 1:44 | Visible in chat, then the first live ask |
| 2:06 | Iterate freely: versions keep every draft |
Where to go next
Agent concepts is the mental model behind the four decisions, and Build your first agent walks them on the screens this version ships — a project agent with a harness, a model, and instructions, put to work on a task. Project agents is the field-by-field reference. The create dialog and the Tools, Knowledge, and History tabs the episode shows are not part of this version; the settings they carried live on the project agent's dialog now.
